5xusb- 3x1394 pci card ? :-) - RJK

Hello, I bought this one, :-
http://tekgems.com/Products/la-pci13.htm  (not from here btw)

...and thought I'd do a  little research, and a restore point ! , before
fitting it.
...partly because I have a card reader in a 3 1/4" drive bay connected to a
motherboard USB pin header - drive letters I:\ through L:\ atm
...2 IDE hd's on IDE1 - drives C:\ through H:\
...2 dvd/cd rewriters - drives X:\ and Z:\  (because I got fed up with them
moving around.)
...a USB pen drive that always seems to appear as drive O:\   for some
reason.

...above links seem to indicate that the two Via VT6306 and VT6214L chips
are already supported in XP (...mine is SP2 updated),

...driver cd that came with it seems to be for something else !
...anyone know what the 2x4 / 8 pin header "JP3" near the internal firewire
port is for ?  ...and what the 5 pin header next to the internal USB port is
for :-)  !

any tips appreciated:-
TIA
